The lines aren't in bad shape. They don't leak at all, and they're not spongy or anything. I can use the line as is. All it means is I'll have to use a different kind of tool to release the metal spring clips inside. I might even be able to make something as a substitute for the OE clip, but I have a pretty full list of other stuff to deal with. Plus, the lines are at least $300.00, which is another surprise expense on top of others that have happened as part of a project in which I intended to replace the radiator, the trans cooler thermostat, trans heat exchanger, a lower temp thermostat, and most of the coolant hoses at the front of the engine. I discovered along the way that my shroud was broken, and I succeeded in somehow breaking one of the fan blades in wrenching the fan clutch off the water pump. On the transmission cooler line connectors, I will change the o-rings for sure...
